Description Oxidized Bitumen 150-5:

Oxidized Bitumen 150-5 is based on Petroleum bitumen which made by Blowning Bitumen 60-70 by hot air.
Bitumen 150/5 means: softening point is 150°c and penetration is 15 desi millimeter is produced in compliance also conformity with ASTM standard.
Oxidized Bitumen 150-5 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air.
This type of bitumen is hard and fragile. In addition, semi-solid oxidized bitumen classify in polycyclic aromatic hydrocarbons. Furthermore, it normally used for different purposes in construction.
Hard asphalt heated double (200 -300 C) against softening point to be flow and viscose.
In addition heating of hard  bitumen oxide should be arranged via hot oil by circulation inside of isolated jacket.
Our Oxidized Bitumen 150-5  also provides in any grade.

Blown Asphalt properties:

Air blowing of vacuum-reduced bitumen causes marked changes in the properties and constitution of material. Blown Bitumen are harder and have higher softening points than the original material and the changes in physical properties appear to be related to the asphaltene content which increases with the temperature and duration of the blowing process.
Analytical data indicate that conversion of the original resins to asphaltenes and the formation of new resins from the oils occur simultaneously. Specs also provide feasible representations of the pathways of bitumen maturation and asphalt deterioration.

Application of  Oxidized Bitumen 150-5: 

Oxidized Bitumen 150-5 furthermore uses in chemical, coating raw material, lacquers, varnishes, paper-pulp-board, textile, pavement ,crack seal and repairmen. Also it uses for civil works, coat piping, roofing, construction. In addition, in sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products.Bitumen 150/5 products are for paving, roofing. Also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf. Furthermore typical uses for bitumen 150/5 include roofing, pipe coating, hydraulic uses.
In addition blown bitumen 150/5 is mainly using in paint manufacturing and coating in hot area.

Technical Advantages of Oxidized Bitumen 150/5

  • Durability
  • Flexibility
  • Water Resistant
  • Chemical Stability

Compared to paving grade bitumen:

  • Reduced temperature susceptibility
  • Exhibits a more ‘solid’ nature at ambient temperatures
  • High penetration index

Storage & Handling:

Heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.
However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.

Note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.

The Oxidized Bitumen material should be broken up prior to placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the Chemical Mine World modified bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flash point of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.
Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.
Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.
For Health and Safety information, please make reference to the relevant MSDS.

Health & Safety of Oxidized Bitumen 150/5:

Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline. Care should be taken when heating oxidized Bitumen 150/5 to avoid over heating

Packing of Oxidized Bitumen 150/5:

Chemical Mine World is the manufacturer of oxidized bitumen 150/5 in various packing, including bitumen 150/5 is available in 20 & 50 Kg Kraft Paper Bags / Poly Amide Bags, 25 Kg Carton box & 150, 180 & 200 kg Steel Drums.
